' THRED-SELECTING DEVICE. f

To all whom #may @mwa/m:

Be it known that I, HOWARD I). Commit, a citizen of the United States, residingl at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Thread-Select-- ing .Devices, of which the following is a specification.

This invention relates to animproved means for taking a single thread from a plurality of threads, as, for instance, from a warp.

In the operation of many textile and other machines operating upon or handling threads, it is necessary successively' to such machines the dividing action must .i both certain and accurate, otherwise th product is likely to be defective.

Threads, though appearing to the unaided eye to be practically uniform in diameter, are not `so in tact. For instance, threads in a common cotton warp, properly sized, often vary in the ratio of one to tour, and each thread, throughout its length, has similar variations. Inaddition to this, threads often have bunches oi at-hielrness many times `the diameter-of the normal thread. A thread-selecting member having a hook adapted to embrace or receive withinit a single thread of normal size vwould not be large enough to receive the larger thread, and would be wholly ineective in taking the bunches; and a thread-selecting member having a hook large enough to embrace one of the larger regular threads (dieren rc ng' for the moment the bunches) treqo n would take two or more of the threads.

To -overcome the diihculties men and to divide with practical certainty, one

. ille? thread from a body of threads at each epinvention.

eration, and, with as great a certainty, not inore than one thread, is the objectv of this This ob]ect `I accomplish by forming the thread-taking device -as a corn- .with a point sufficiently sharp and tapering to penetrate into the substance of athread which :for any reason does not pass to the Specicaton of Letters fatent.

inner side ofthe point and seat itself Within Ithe pdclret; by the mechanism herein shown and described, all threads excepting those that at the points in their lengths acted upon by the thread-taking device are small enough to enter the hook opening, are

speared `or impaled by the sharp point of therhcok, and moved into position for the next succeeding step in the operation of the thread handling machine. In a similar manner, hun ies upon the threads, in the line` of operai n of the threadtaking de-` vice are imp d upon the sharp point of the hoch, a1 the 'threads carrying such h.. ches` I have i i said invention in its application. tc the warp-tying machine illustrated and described in my'British Patent No. 10,484 ct l905. The drawings of the present application show only so much of said warp tying machine as is necessary to give an understanding ot this invention.

In the accompanying drawings, Figure l 1s a 'fraginentai side elevation of the main carriage of the warp-tying machine above alluded to. Fig. 3 is a sectional detail View taken on the plane of dotted line 2 2 of Fig. l. Figs. 3 and Si are respectively fragmental edge and side views, greatly enlarged, of that element of the threadftaking mechanism which directly engages the warp threads, which element will he hereafter referred to as the selector. Figs. 5 land S are similar views et a selector havin a hook rom that illustrated in 3 a view orf a select i' views l iid 9 vare detail g action of the ability for taking threads or difieren. i. eters.

In the Warp-tying .machine hereinbefore 2 is an edgeV ioo referred to, the two Warps a: and to be tied together are' supported in twosubstantially parallel planes, the thread-taking mechanism is supported upon a carriage 1, the base 2 of which carriage is slidably 'mounted upon the bed 3 of warptying machine. The carriage i is moved by suitable means (not herein shown) to more the thread-tak v 4: and rcarries a selector, to be hereinafter The eecentricsl() and ill.'-

Said thread-taking mechanism is adapted to take one thread from each warp and move toward each other the threads so taken. The thread-taking mechanism comprises two selector levers 4 and 5 provided with bearing openings 6 in their rear ends, by means of which openings said levers are pivotally mounted upon studs 7 extendin from a standard 8 fixed to the base 2 o the carriage l. Each of the selector levers described, and said levers .are 'pivotally moved toward and away from each other to reciprocate ,said selectors across the lanes of the warps a and 6.# The means ereing Ltfand 5 c oniprisesa shaft 9 driven lby any suitable means, which shaftAhas-two @eeen-l.' triesl lll'a'nd 11 fixed with relation'thereto. .A11 opening 12is formed "mvthefselectorle'- lver 5, and insaidgopeningjsslidably supported a block; ha'vingfan'Z opening llt therein, in which opening.'lllv the eccentric lever and having in'di'tsfethei'* enden open ing 15a within whichii jthefle'ccentric 10..

The louter ends of. the arms of said fork are provided with alined o enin'gs 18 and'l), the former'being screw-t eaded to. receive a cone. bearing'screw 20, The open-- ing 19 is scmewhatilarger than' the opening adjusting'-v disk ystem-:Q being' externelly screw-threaded vat itsendand'proVided with/a linnaieefthtimbint Qdi-for clamping forlgarm, The stem 21' isa'xially 'perforated interxiaily 'screw-threadedto receive a cone bearing? screw 24e similar to the screw 20, which screw 2li has 'a lock nut 25. Bei' tween the screws 20 and '24 is rotatably supported asocket member 26 provided with trunni'ons :27 and 28, said trunnions being cupped at theirv outer ends to receive the points of said screws. L The socket member 2G has an openind, 29 .extending theref a stop pinO. Upon the trunion 27 is iiredoa stop varm 31. A' spring 32 is coiled about 4said trnnnion, one end of said spring engaging the stopf'arm" and the v`other en engaging a. pin Stien-t tensiowadjusting dish 22. The stopv arm 3i@ portion being roundef,

is' adapted' to engage one end of an oscilla' tory' stop linger 34 pivotally` mounted loetween the ears 35 secured to the fork 16. The other end of said stop finger is bifur- .catedto receive a pin 36 extending transversely from a piece 37 fixed with relation to the carriage 1.-

'A selector 38 is secured within each of the .socket members'26 by means of neet-screw 39 lying in a threadedopening in said socket and' bearing aglainst a flattened portion of said selector. he selector 38 .has a round body portion tapering slightly toward its operating end. -At its smaller end the vselector 1s cut away at two diametrically opfposte sides to form a attened, blade-like portion 40, the outer end of said. atteed as shown at 41, Figs'. 3 to 6'.v In one edge o y p l y lrtion, is formedy af'hook-V 42. The 'edge o lthe enter end of said vflattened. ortion forms one side of said hook and-isa ined therewith. i. The

'said flattened portion'v ,and between theends of said otherv side 43 of the hook 42 is pointed 'or sharpened in the direction of its lengthl and its'breadth, so as to make said side of the hook conical or tapering. The size and form ofthe opening between the sides of the hook, as well as the degree of taper of said pointed end, are varied A to' adapt the selector to threads of different counts` and qualities.'

The edge of the flattened portion 40 to the rear of the 4hook may be slightly inclinedto'- ward saidrhook, as shown in Fig. 4, the better to adapt it to handle threads under certain conditions.

In operation, the shaft 9 is rotated, pivot-- "ally moving the selector levers 4 and 5 alter vnately toward and away from each, other,

and reci rocating the selectors 38 across the planes of the warps a and The .spring 32 ward against the vforemost thread of its warp.v lhe force exerted bylsaid spring is i0r vholds* each of said selectors yieldingly for; o

adjusted by means of the tension-adjusting;

disk 22, the limit of the forward move-K ment of said selector due to said spring is determined by rthe stop-inger 34', the for lwardend of which finger engages the stop arm 31 rigid with said selector. At the extremity of its outward movement, that is to say, at the end of its movement away from its war i, the selector lies with the'edge of the 'blade-like ortion 40, below the hook 42, incontact witi the foremost threadI of the warp. In its inward movement, the selector, sliding against said foremost thread and be ying guided by said lower portion',ibri n`gs its hook into engagement with the thread- If thethreadjbe small enough, it passes; within the hook opening, as shown in Figli). If it be too large to enter said o ening, or if a bunch occur in the thread at theivpoint ofengagement-of theselectoi, the sharp point 43 of the hook spears ,ortimpales the thread or bunch, as the casemay'be, as represented in lli:

Figs. 8 and 9. Whatever the mannerfo'engagement of the selector with ,the thread, the

continuing inward movement of the selector moves said thread toward the opposite -warp to aiiextent suiiic-,ient for another mechanism of the warp-tying machine to engage the thread. Being pivotally supported., andfree to swing rearwardly, the selector is able to adjust. its position to whatever tension' the thread divided, as 'just described, from its warp, may have. Uponiits outward movement the forward pivotal spring-actuated movement of Athe selector is restrained and governed by the engagement ofthe stop arm 31 with the pivotal stop iin er 34:, which stop ingeris positively move by reason of its connection with its selector lever and the fixed piece 37. Said stop finger also limits the pivotal movement of said selector, so as to prevent it from springing beyond the plane of its warp when no threads are presvided for Awarps of different counts and ent. As successive warp threads are taken by the selectors, thecarriage 1 is ted toward the warps a. and b by a sensitive feed mechanism, (not herein shown). Selectors having hooks of various' sizes and forms are proqualities. I

It is clear that selectors might be fashioned in a di'erent manner from that shown and described herein and be operated in different ways, without departing lfrom the spirit and scope of my invention; wherefore lI wish it understood that said form is merely illustrative of said invention and its application.
